Netflix ISP Speed Index for May

We just added May data to the “Netflix ISP Speed Index,” providing an updated look at which Internet Service Providers (ISPs) provide the best Netflix streaming experience.

A few data points from the new Netflix ISP Speed Index, reflecting data for May:
  • U.S.: The top rankings remain unchanged, but the top five ISPs all delivered slightly faster averages. Optimum continues to provide the best Netflix experience of any large ISP, followed by COX. 
  • U.K: No change in rankings with Virgin holding on to its top position. All ISPs in the UK delivered improvements in speed in May compared to April. 
  • Ireland: UPC dropped three spots to No. 4 while Magnet maintains its No. 1 slot and continues to be the ISP with the best Netflix performance. Runner Digiweb, Eircom and Vodafone showed slight speed increases. 
  • Nordics: Average speeds went up for each country. The Nordics continue to have the fastest ISPs, led by Ownit in Sweden. In Norway Altibox jumped back to the No. 1 slot 
  • Mexico: Speeds increased for the top three providers, giving Netflix members who use those ISPs a better experience.

Located at the Netflix ISP Speed Index provides an easy overview of the performance of ISPs in several of the countries Netflix is available in. Updated on a monthly basis, the site allows for easy comparison of ISPs in a country as well as international comparisons.

The Netflix ISP Speed Index is based on data from the more than 36 million Netflix members who view over 1 billion hours of TV shows and movies streaming from Netflix per month. The listed speeds reflect the average performance of all Netflix streams on each ISP's network and are an indicator of the performance typically experienced across all users on an ISP network.

Note: the average performance is below the peak performance due to many factors including the variety of encodes Netflix uses to deliver the TV shows and movies as well as the variety of devices members use and home network conditions. These factors cancel out when comparing across ISPs.
